Hi.

I'm always fighting with my distribution.
I use the last release of Buildroot with an external Toolchain (to use 
glibc and no uclibc) made with last version of Crosstool-ng.
During compilation I have some errors.

The first one is during nano compilation, and I found nothing to help me 
for now. The log :

files.c: In function 'get_full_path':
files.c:999: warning: ignoring return value of 'chdir', declared with 
attribute warn_unused_result

I have the feeling that it is searching for a bad version of a library. 
Or maybe there is a compatibility problem between nano code and library 
inside the toolchain?

As I didn't understand this, I tried to delete nano from configuration 
of buildroot and come back to this later. But now it's less compilation 
which fail.
The log :

Erreur 2

So here I found that there is a link with ncurses library. As nano too 
is linked to ncurses, I wonder if there is a problem with it.
Buildroot use ncurses 5.6 and Crosstool use 5.7. Maybe it's the problem, 
but how to repair this?

If I try compilation without less, the exactly same error as the first I 
quote appear again during ts_calibrate compilation (tslib tool).

Someone has an idea for this?

Thanks,
Damien.
